Application November 18, 1933, Serial No. 698,641 '13 Claims. (01.74-103) This invention relates to new and useful improvements in beamhangers.

One object of the invention is to provide an improved beam hanger forsuspending from the walking beam the polish rod of a well pumping rig,whereby a straight lift is provided for the rod and certain otheradvantages are obtained.

A particular object of the inventionis to provide a beam hanger whichmay be adjusted with a stick from the floor of the derrick, thusobviatingthe necessity of climbing upon the beam or the use of tools..

A further object of the invention is to provide a beam hanger in whichthe parts are held in positive relation to each other and. also in whichAconstruction designed to carryout the invention will be hereinafterdescribed, together with other features of the invention,

The invention will be more readily understood from a readingof thefollowing specification and by reference. to the accompanying drawingsin which an example of the invention is shown, and wherein: V

An ordinary walking beam A is hinged upon a Samson post 3. The polishrod 0 is illustrated as extending from the stufling box D of the casinghead. The walking beam is operated in the usual manner, which it is notbelieved necessary to describe. i V V I In Figures 1 to 6 inclusive, thenumeral 10 designates a T-hanger. This hanger has a trans-V verse rockerbar 11 across its top adapted to engage in the usual notches E on top ofthe beam g and upon each side of the-slot F in the end of said beam, Theshank'of the hanger extends down through thisslotand is free to swingthere in. At the lower end of the hanger 10 and a substantial distancebelow the beam, a clevis 12 is provided. This clevis is made integralwiththe, hanger, extends rearwardly and has a pair of op, positeapertures 13 and a pair of opposite apertures 14, as is best showninFigure 6. The apertures13 underlie the shank of the hanger, while theapertures 14 are offset rearwardly therefrom. i

ed in the aperture 13 of the clevis 12, whereby said link is suspendedfrom the clevis andoverlies the upper'portion of the rocker 18. Thelower end of the link 21 is pivoted at 23 to the upper end of aninverted IT-hanger 24. The. rocker is provided'with a recess 25 forreceiving the joint 23 and permitting the link 21 andinverted T-hanger24 to lie upon the face of the rocker when it is swung to its upper,position, as is shown in Figure 3. Hanger rods 27 are pivoted on thelower end of the inverted T-hanger and these rods support a clamp 28 andare disposed on eachside of the polish rod C, which has its.

upper end fastened in said clamp. v

It will be observed that when the walking beam A is in its central orintermediate position, as is shown in Figure 1, the pivots of the link21 and T-hanger 24 and all of the parts therebelow are verticallyalined. When the beam is swung downwardly from this position to theposition actor-shaped head 15 is provided with, an aperture 16 forreceiving a pin 17, which engages One oftheimportant features of theinvention resides in' the means for controlling the swinging of the headand for holding it in proper position to support the link and invertedT-hangersv' when necessary. Co-extensively with the bottom bar is aslidable stop bar 29. This "barextends through a guide loop '30 atthetop of the 15 bar 20 and a second guide loop 31 -near-the upper endof said bar.

20 pivoted to an ear 34 (Figure 7) so as tohang from-"the head- -and" toengage the ratchet teeth 32, as is best shown in Figure 5.

The tendency of the' stop bar 29" is to slide downwardly thus causingthe teethof its .rack 32' bar-29 *can beslid upwardly until the" dogridesout of engagement with the ratchet teeth, as" is shown indottedlines 'in Figure 5. When this 30 oc'curs; the-stop bar willbereleased and will be free-toslide downwardly along the bottom bar- 20?-Itisobvious that a workman standing on the I the spirit ofthe-inventions.

floor of the derrick may reach "the-- dog =-with stick or pole and swingthe same -=upwardly to release the stop bar without climbing onto the Ifhe wishes to elevatethe stop-bar, he merely has-to place hisstickagainst-the lowerbeam:

ratchet teeth willpass throughthe dog whenth-i's The" stop bar 29' isprovided at its upper end with a fla't cap'35i' Astrik-pad=36-made'of"rubrespect to said head;

br belting "or any "other suitable-material is fastened on the underside of the beam A so---as-" tobe engaged by the cap 35*to-cushion:the-swing of the "head 'l5 'and 'alsoto protect the" beamagainstwear-rIt'will be observed-that'when the A stop bar slidably supported by thehead and -pro beam swings downwardly from its position shown in Figure 1to its position shown in- Figure 2, the, link"21andthe inverted'T-hanger 24 will tend to swing the 'hanger'lO to a vertical position;where by"th'e' head 15; "owingto" its ofiset-pivot-l'l, will be "soswungas to carry the rocker 18' away-from" said links, therebynotinterfering with the ver ncaraimement of the links and the partst-herebelow."

When .the beam reaches the intermdiateportion of its swing the capwill-Yengage the pad and prevent ,further swinging of the hanger and.head. This will cause the rocker .18 tobeswung'into contact,

A yoke-shaped dog 33 straddles the two bars and is to"swing-the dog-33E downwardly and thus support said bari- By swinging thedog upwardly, the

i the invention, which. is .seteforth'asinew anchuseszw obvious that astraight lift of said rod is had during the entire operation. 7

In Figures 10 and 11, I have shown another form of the invention whichisadapted to be used in connection with a walking beam A, the 5 end ofwhich is not provided with a slot F. With this type of beam there is noway of supporting the I -hanger 10,-so I provide .in placeeoi saidhangeraa stirrup 1l0."iwhichengageseover the end of the beam A (Figure10). The stirrup has a clevis 12, similar to the clevis 12, at its lowerend. This clevis is preferably made integral with the-stirrup, extendsrearwardly, and has a 'pair of opposite apertures 13- and apair'ofopposite apertures l4,-as is best shown in Figure 11; The

apertures 13' underlie .the stirrup, while'the apertures 14E arerearwardly therefrom. The apertures'l3' have'the-upper end of the link21 pivoted therein on the pin 22 and the pin 17 pivotally supports thesector-shaped head 15 inthe apertures 1 14 :9.
